IMPROVEMENT IN ELECTRO-MAGNETIC GAS-LIGHTING APPARATUS.`

Specification forming part of Leiters Patent No. 116,05,da.ted June '20,1871.

To all whom t may concern:

Be it known that we, FRIEDRICH HEYL and PHILIPP DIEHL, of East New York,in the county of Kings and State oi' New York, have invented a new andImproved Electrical Igniting Apparatus 5 and we do hereby declare thatthe following is a full, clear, and eXact description thereof, whichwill enable others skilled in the art to make and use thesanie,reference being had to the accompanying drawing forming part ofthis specification, in which- Figure l represents a side elevation,partly in section, of our improved electrical igniting apparatus. Fig. 2is a plan or top view of the same.

Similar lettersrof reference indicate correspon ding parts.

This invention relates to a new arrangement of devices for bringing' theelectric spark in contact with the jet of hydrogen gas which escapesfrom a zinc-and-acid reservoir similar to Vthat used in the Doebereinerlamp 5 and has for its object to dispense with the platinumsponge, whichis expensive and too rapidly de'- stroyed, besides being easily affectedby moisture or other change of temperature. Our invention consists inthe connection, with the valve-lever pertaining to the said reservoir,of a projecting prong and one conductor of electricity. The otherconductor leads to a serrated or corrugated plate, which projects fromthe top of the reservoir. When the lever is moved to open the valve andpermit the escape of gas, the projecting prong is, by the same motion,brought in contact with the serrated plate, closing thereby the circuit,and

- producing a series of sparks which ignite the gas. The burning jet canbe used to ignite other things, either the wick of a lamp, a taper, orother article. The prong and plate can be made of steel or other metal,and are more durable and reliable than the platinum-sponge.

A in the drawing represents the vessel or reservoir, within whichhydrogen gas is created in the well-known or suitable manner.` B

is the cover of the vessel A. From it projects a tube', a, for theescape of the gas. b is a valve fitted through the tube a for preventingor regulating the escape of gas. C is a lever atlixed to the valve forturning the same. A spring, al, or weight tends to so hold the leverthat the valve will be closed, as shown in Fig. 1. D is an electricbattery of suitable construction. Itsvone conductor, E, is connectedwith the lever C, the other, F, with a plate or post, c, projecting fromthe upper end of the tube a. The plate e of the pivot of the lever C isinsulated t'roni the metal of thetube, so that the electrical circuitwill not be established unless the lever is brought in direct contactwith the plate e. To facilitate this a projecting prong, f, is aflixedto the lever. Both the plate e and prong f can be made of steel or othersuitable metal.

When the lever is swung up to open the valve the prong f is brought incontact with the surface of the plate e and moves over the same. Weprefer to corrugate or roughen the surface of e so that greater frictionand consequent lnore absolute contact will be produced when/the prongmoves over the plate. Thev electric circuit is then completed, and thecurl rent passes through the conductors. emitting sparks as it passesfrom f to e, or vice versa. As at the same time the valve a, has. beenopened to permit an escape of hydrogen gas the sparks will come incontact with the gas, igniting the same, and enabling it to ignite otherbodies.

Having thus described our invention, W'e claim as new and desire tosecure by Letters Patent- The combination of the valve a, lever C, andprong f with the projecting plate e and el c tric conductors E F, allarranged to operate substantially as herein shown and described.

FRIEDRICH HEYL.
